Abstract: 286,768. Brackensey, A.. H. Dec. 7, 1926. Optical records and apparatus.-In the reproduction of sound from photographic and like records by the projection therethrough of a beam of light on to a photo-electric cell connected through an amplifier with a loud speaker, and endless record in cylindrical or flat ring form is employed, carrying an endless trace or traces each corresponding, to a single note so that any particular note recorded thereon can be repeated or sustained without any wear of the trace. Further, by employing a series of such records recorded with different notes or sounds, and controlling a shutter or shutters in the path or paths of the beams, or the circuits of the various photo-electric cells, from a keyboard device which may be operated manually, mechaniaally, electrically, oiautomatically by a jacquard sheet of the like, different sounds may be reproduced separately or in combination as desired. Variation of the individual sounds can be effected by varying the intensity of the beam or beams, or introducing variable damping resistances, constant or fluctuating in the output cell circuits by the keyboard device. Fig. 1 shows an endless cylindrical photographic record 1 mounted on a transparent roller 2, or to overhang an opaque roller, suitably rotated. A beam from a lamp 3 is projected through a movable shutter 11 on to the record and thence to a cell 4 in a circuit containing an amplifier 9 and loud speaker 10. The shutter 11 is supported on a spring 11<a> and can be actuated to shut off the beam by a relay 13, 14 controlled from a keyboard 12. In a modification the shutter 11<a> is replaced by a fixed screen within the cylinders, and the keyboard contact is in the cell circuit which can be made and broken thereby. Fig. 4 shows the record in the form of a flat ring 1 mounted on a transparent rotary disc 16; the keybord contact 12, 12a is in the output circuit of the cell 4.

Filed: 1924-12-24
Abstract: 249,603. Gramophone Co., Ltd., and Mittell, B. E. G. Dec. 24, 1924. Magnetic instruments.-An electromagnetic recording and reproducing device is constructed so that the magnetic flux passes through three or more relatively movable components, some of which are not required to rise and fall with the record surface. Preferably only the lighter parts, including the stylus, have vertical movement and these parts are partially balanced. In one arrangement, the permanent or electromagnet 1, Fig. 1, is supported so as to be stationary or move only parallel to the turntable, and the pole shoes 8 and a former 13 carrying coils 11, 12 influenced by the audio frequency currents are carried on arms 4 pivoted on a bracket 2 fixed to the magnet 1 and counterbalanced by an adjustably weighted rod 5, whereby the shoes and coils can move vertically between the limbs of the magnet to follow irregularities in the movement of the record in its plane. The stylus 21 is carried by an armature 14 of magnetic material split longitudinally to reduce eddy currents and mounted with clearance within the former 13 on pivots 17, 18 carried by a bracket 7 at one end of the arms 4 and the cover plate 10. The upper end of the armature is flattened and rests between blocks of felt or other damping material supported from the pole shoes and tending to centralize the armature. In a modification, the pole shoes are fixed to the magnet and the frame carrying the coils and the pivoted armature is mounted on the pivoted arms, the damping blocks being carried from the coil frame and engaging the lower part of the armature. In a further modification, the stylus 21 is carried from a vibratable coil 2, Fig. 4, pivoted horizontally on a curved core 24 supported by a bridge 23 from the pole pieces 8, 9 which are balanced and have small vertical movement between the limbs of the magnet 1, as in Fig. 1. Damping blocks 19 carried by the pole-pieces bear against the stylus mount 26 and tend to centralize it. Detail modifications comprise the support of the armature by a flat spring instead of pivots, liquid damping and centralizing by a spring.

Title: Improvements in and relating to means for supporting and moving films in sound recording and like apparatus
IPC: G03B31/02
Filed: 1929-10-14
Abstract: 331,785. British Thomson-Houston Co., Ltd., (Assignees of Heisler, C. L.). Oct. 13, 1928, [Convention date]. Addition to 321,660. Kinematograph apparatus.-Relates to apparatus for driving a photographic film record, such as a sound-record, and consists in providing means whereby the opening movement of the door of the casing of the apparatus effects the rotation of a bell-crank lever carrying one of a pair of separable rollers between which the film passes, the bell-crank lever also serving in its movement to rotate a second lever carrying at least one of another group of separable film-engaging rollers. In the construction shown, the film is guided and moved through a casing 1 by a sprocket 11 and a drum 12, being pressed against the sprocket by a roller 13 carried by an arm 28, and against the drum 12 by rollers 14, 15 mounted on a yoke 32. The arm 28 is part of a bell-crank lever consisting of arms 27, 28 projecting from a spring-influenced sleeve 24, and the yoke 32 is pivoted at 33 on an arm 34 carried by a spring-controlled sleeve 25. The arm 34 also carries a spring 36 acting on the yoke 32. An adjustable screw 40 on the arm 34 engages the arm 28, which is operable by a rack 41 protruding through the wall of the casing. The rack engages a pinion 42 surrounding the hinge pin 5 of the door, and is of such a length that when the door is swung open through more than a right-angle the rack moves the arm 27. This raises the arm 28, lifting the roller 13 from the sprocket, and at the same time the arm 28 raises the arm 34, thus lifting the rollers 14, 15 from the drum. A detent 44 engages a notch in the each 41 when the door is fully open, and holds it in that position. An idler 16 engages a loop in the film to control the relative speeds of the drum and sprocket, as described in Specification 295,378, [Class 40 (ii), Phonographs &c.]. This idler is engaged and held raised by a hook 45 attached to the arm 27, when the door is fully open.

Abstract: 1,199,063. Position encoders. J. F. SCHUGT. 7 July, 1967 [8 July, 1966], No. 31508/67. Heading G4H. [Also in Division G1] A transducer for measuring angular speed or position comprises a circular rotatable disc having elements 14 around its periphery which affect the coupling between coils 11, 12 wound on ferromagnetic cores 44, 51, the flux path between the coils being confined to increase the sensitivity of the transducer by surrounding each coil with a conductive shield except in narrow areas defining the flux path. Thus the coils are surrounded by shields 40, 41, 45, 53, 49, of which shields 40, 41 are made wholly of conductive material, e.g. aluminium, with gaps 42, 43 provided for the return flux. Shields 45, 53, 49 may also be made wholly of conductive material with gaps 50, 56 defining the flux path. Alternatively, they may be made of copper coated insulating material, e.g. fibre glass, with the conductive coating etched away to provide the necessary gaps. The slots in shields 40, 41 may be omitted, the cylindrical shields being increased in diameter to include the transverse shot between shields 49 and 53 within its circumference so that the return path of the flux lies inside the cylindrical shields. Insulating end plates 56, 60 are arranged at the remote ends of the coils, carrying terminals 57, 58, 61, 62 for the coils. The assembly is held in position by a potting compound and attached to a supporting conductive member 33, Fig. 3 (not shown). The rotating disc may be made of conductive material with conductive or ferromagnetic teeth 14 or a combination of both, e.g. conductive teeth with a ferromagnetic inlay. Alternatively the disc may be made of insulating material with conductive segments (72), Fig. 6 (not shown), printed round its periphery. In operation the coil 11 is connected to the output of an H.F. oscillator, the coil 12 forming a regenerative feedback to the oscillator, so that in the absence of a tooth the oscillator is maintained in oscillation and stops oscillating wnen a tooth is positioned between the coils. The output from the ocillator is fed via a demodulator to a Schmidt trigger circuit to provide a square wave output. The oscillator may be connected to a multivibrator whose oscillations will only be maintained in the absence of a tooth between the coils.
